UNITED STATES PATENT OFFICE.

STANCHION.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed July 3l, 1906. Serial No. 328,607.

To LM whom, t may concern:

Be it known that I, FRANK S. OvEnAcKER, a citizen of the United States,residing at Stella, in the county of Oowlitz and State of Vashington,have invented certain new and useful Improvements in Stanchions, ofwhich the following is a specification.

This invention relates to stanchions.

One obj ect of the invention is to provide a stanchion for securing acreature in a stall or place in such manner as to allow more or lessfreedom of movement whether the animal be standing or lying.

Another obj ect of the invention resides in the provision of a simple,inexpensive, durable, and eflicient stanchion embodying such othercharacteristics as will facilitate its quick and easy manipulation.

lVith the above and other objects in view the present invention consistsin the combination and arrangement of parts hereinafter moreparticularly referred to, shown in the accompanying drawings, andparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of my invention. Fig. 2is a vertical sectional view. Fig. 3 is a detail view of the guiding andlimiting member, and Fig. 4 is a detail view of the latch.

Referring now more particularly to the accompanying drawings, it will beseen my improved stanchion may be supported in a suitable framework forerection in a stable, shed, or other place and comprises in itsorganization base and head members 1 and 2, respectively, connected atsuitable intervals by the vertical members 3, with the stanchiondisposed in the openings between them; It will thus be understood thatmy improved stanchi on may be one of a series or that one only may beused. As all the stanchions would be similarly constructed andsupported, one only will be herein described.

Secured to opposite sides of the base member 4 are straps projectingbeyond each end of the base member to form spaced sets of ears 6 and 7,for a purpose presently eX- plained. A guiding and limiting member 8,preferably U shape, is secured to the head member 4 and projects beyondthe ends of the head member, forming at one end thereof the spaced ears9, which latter aline with the spaced ears 6 to receive the verticalstationary bar 10. Pivoted at its lower end in the ears 7 is a swingingbar 11, whose upper end moves and is guided in the aforesaid limitingand guiding member 8, the outer end of the latter being closed andslightly contracted to create a binding action upon the movable bar whenswung from the stationary bar to limit its movmeent and preventaccidental backward movement upon its pivot.

When the pivotedbar is thrown into parallellism with the stationary barto cooperate therewith, means should be provided to hold the pivoted baragainst accidental movement upon its pivot, and I therefore provide thepivoted latch member having the legs 13 and the aXis 14, upon whichlatter is loosely mounted the roller 15, designed to rest, normally,upon the upper edge of the guiding and limiting member 8. The upperextremity of the pivoted bar 11 being beveled, as at 16, it permits thebar to pass under the roller 15 and lift the latch upon its pivot a,until the pivoted bar engages the adjacent end of the head member 4',when the latch will drop and dispose the roller 15 back of the pivotedbar and hold the latter firmly in coperative relation with thestationary bar 10. It will thus be understood that the roller 15 reducesfriction, and that therefore just as soon as the animals head is inproper position the pivoted bar may be snapped quickly in parallelrelation with the fixed bar 10 to hold the creature comfortably againstrelease. While not absolutely necessary, I may employ a spring 16,having one end adapted to cooperate with the latch to limit the upwardmovement thereof.

My improved stanchion is pivotally mounted, there being upper and lowerpivots 17 and 18, respectively, working in the perforations 19 of thebight portions 20 of the corresponding upper and lower U-shaped straps21, secured in any suitable manner to the base and head members 1 and 2of the frame in which the stanchion is mounted. It willv be seen thatthe upper pivot pierces the spring 16, but it is to be understood thatthis spring may be dispensed with, if desired.

at is claimed ish 1. A stanchion comprising a stationary member, aswinging member, a member embracing both members to guide the swingingmember and to limit the outward movement of the latter, the outer end ofthe guiding and limiting member being contracted to create a bindingaction upon the swinging member when the latter is swung outwardly,

and a latch to hold the stationary and swinging members in operativerelation to each other. Y

2. A stanchion comprising a stationary member, a swinging member, amember embracing both of the aforesaid members to guide and limit theoutward swing of said swinging member, the outer end of the guiding andlimiting member being contracted to create a binding action therebetweenand the swinging member when the latter is thrown outwardly, a latchmember to hold the stationary and swinging members inloperativerelation, and a roller carried by the latchA member to reduce frictionbetween the latter I5 and swinging member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
